Each student in a class of 25 students wrote down a random digit. what is the predicted number of students who will win a digit that is greater than 7?

Answers

Comment
I'm going to assume that 0 is below 1 and not above 9. Furthermore that there are 10 digits altogether.

Argument
I may not understand the problem, but I think it means that how many students will randomly choose an 8 or 9.

Since both can come up (randomly) 1/10 of the time, it would seem to me that the answer should be

1/10 * 25 + 1/10 * 25 = 5

so 5/25 students will come up with an 8 or 9.
so P(8 or 9) = 0.2 <<<< answer

Note
Any two digits should give you the same result.

That makes a right triangle 8 - -3 = 11 in the x direction, 5 - 1 = 4 in the y direction.

d² = (8 - -3)² + (1 - 5)² = 11² + (-4)² = 121 + 25 = 146

d = √146 = 12.083045973594572

A student sales neckslaces to earn eztra money. She charged $10 per necklace for material and $2.75 per hour to make unique gifts. How much would two necklace cost together if one takes her an hour to make and the other three hoursto make?

Answers

Answer:

Final answer: $31

Step-by-step explanation:

Okay, so, 2 necklaces would be $20.

One hour would be + $2.75

Three hours would be + $8.25

So all the hours together would be $11

Then, you add $20 + $11 to get $31.

At its highest point, the elevation of a county is 5,776 feet above sea level. At its lowest point, the elevation of the county is 6 feet below sea level. Write an expression using integers to represent the difference between the elevations.
(Do not simplify.)

Answers

The expression that represents the elevation is 5,776-(-9)=5,785.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that at its highest point, the elevation of a county is 5,776 feet above sea level. At its lowest point, the elevation of the county is 6 feet below sea level.

The expression will be generated by subtracting the two heights.

5,776-(-9) = 5,785.

Therefore, the expression that represents the elevation is 5,776-(-9)=5,785.

The expression below is a sum of cubes. 125x3 + 169

Answers

Answer:

$\text{The expression }125x^3+169\text{ is not the sum of cube}$

Step-by-step explanation:

Given the expression

$125x^3+169$

we have to tell the above expression is the sum of cube

The sum of cube is of the form

$a^3+b^3$ → (1)

$Expression: 125x^3+169$

125 is the cube of 5 and 169 is the square of 13

$125x^3+169$

$(5x)^3+13^2$

Comparing above with equation (1), we see the given expression is not the sum of cube

125x^3 = (5x)^3
125x^3 is the cube of 5x.

169 = 13^2
169 is the square of 13, but not the cube of a rational number.

The statement is false.

B(n)=2^n A binary code word of length n is a string of 0's and 1's with n digits. For example, 1001 is a binary code word of length 4. The number of binary code words, B(n), of length n, is shown above. If the length is increased from n to n+1, how many more binary code words will there be? The answer is 2^n, but I don't get how they got that answer. I would think 2^n+1 minus 2^n would be 2. Please help me! Thank you!

Answers

Answer:

More number of words that can be made: $\bold{2^n}$

Please refer to below proof.

Step-by-step explanation:

Given that:

The number of binary code words that can be made:

$B(n) =2^n$

where n is the length of binary numbers.

Binary numbers means 2 possibilities either 0 or 1.

Here, suppose if we have 5 as the length of binary number.

And there are 2 possibilities for each digit.

So, total number of possibilities will be $2* 2* 2* 2* 2 = 2^5$

If the length of binary number is 2.

The total words possible are $2^2$ .

These numbers are:

{00, 01, 10, 11}

If the length of binary number is 3. (increasing the 'n' by 1)

The total words possible are $2^3$ .

These words are:

{000, 001, 010, 100, 011, 101, 110, 111}

So, number of More binary words = 8 - 4 = 4 or $2^2$ or $2^n$ .

So, the answer is $2^n$ .

Let us try to prove in generic terms:

$B(n) = 2^n$

Increasing the n by 1:

$B(n+1) = 2^(n+1)$

Number of more words made by increasing n by 1:

$B(n+1) -B(n)= 2^(n+1) -2^n\n\Rightarrow 2* 2^(n) -2^n\n\Rightarrow 2^n(2-1)\n\Rightarrow \bold{2^n}$

Hence, proved that:

More number of words that can be made: $\bold{2^n}$

Final answer:

When the length of a binary code word increases from n to n+1, the number of additional binary code words is equal to the number of binary code words of length n, which is $2^n$ .

Explanation:

When the length is increased from n to n+1, the number of binary code words of length n+1 is equal to the number of binary code words of length n multiplied by 2. This is because for each binary code word of length n, we can append a 0 or a 1 to create two new binary code words of length n+1. Therefore, the number of additional binary code words is equal to the number of binary code words of length n, which is $2^n$ .
